TIRE-PROTECTOR. I

Specification of Letters Patent.

Patented NOV. 26, 191 8.

Application filed July 26, 1915. Serial No. 42,088.

To all-whom it may concern:

Be it'known that 1, PETER L. HARVEY, a citizen of the United States, andresident of Des Moines, in the county of Polk and State of Iowa, haveinvented a certain new and useful Tire-Protector, of which the followingis a specification.

The object of my invention is to provide a tire protector of simple,durable and inexpensive construction.

A further object is to provide a tire protector made in units soconstructed and arranged and mounted on the tire that any of the unitsmay be quickly andeasily disassembled for the purpose of replacing orrepairing any of the elements of the particular unit.

Still a further object is to provide such a device made in units soconstructed and arranged that each unit may be mounted on the tireindependently of the other unit without interfering with or beingdependent thereon.

A further object is to provide such a protector which may serve thepurpose of an anti-skidding device.

Still a further object is to provide such a protector so constructed andarranged and provided with such parts as to make the devicesubstantially noiseless when in use.

My invention consists in the construction, arrangement and combinationof the various parts of the device whereby theobjects contemplated areattained as hereinafter more fully set forth, pointed out in my claimand illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of a portion of a tire equipped with aprotector embodying my invention. and

Fig. 2 shows a vertical sectional view through the tire showing one ofthe pr0- tector units in front elevation.

In the accompanying drawings, I have used the reference numeral 10 toindicate generally the casing of an ordinary pneumatic tire, of theclencher type, mounted on the rim 11. My protector comprises a pluralityof units. The method of mounting the same on the tire will now bedescribed.

I provide an annular member adapted to be placed on each side of the rimand having a curved portion 12 arranged to fit on the inside of thecurved portion of the rim, and a member 13 inclined outwardly from the23 is. provided with center of the whee and also laterally, as shown inFig. 1.

Formed on the outer'edge of the portion 13 is a plurality of spacedbearing members 14. Suitably mounted in the bearing members 14 is a rodthe bearings 14 are successive notches 16 formed in the portion 13 ofthe annular tector comprises on each side a ink having a body portion17, and at its inner end a curved hook member 18 adapted to be placedover and to receive the wire or rod 15.

The outer end of the link 17 is provided with a pair of spaced'outwardlyextending bearings 19, which register with each other.

members Each unit of my improved 'pro- Each unit has a plurality oflinks, each com-- prising a body portion 17 similar to that alreadydescribed, and a central inwardly extending bearing 20, and a pair ofspaced outwardly extending bearings 21, the openings in which registerwith each other.

The inner bearing 20 of one link is placed between the bearings 19 and abolt 22 is extended through one bearing 19 and screwed into the otherbearing 19.

The inner bearing member 20 of each of the other links is inserted btween the bearings 21 of the next inner adjacent link, and is pivotallyconnected thereto bv means of a similar bolt 22 extended through one ofthebearings 21 and screwed into the other bearing 21.

The central tread portion of each unit of my improved tire protectorcomprises a body portion 23 having a curved or concave lower face to fitthe tire and a substantially parallel upper face. At each end the body alaterally extending lug 24. having an opening through it. The lug 24 isdesigned to be extended between the bearings 21 of the outer link of theseries on each side of the tire, as Sl.OWI1 in the figures, and to besecured thereto by a bolt 22.

Near each side of the body 23 on opposite sides of the central treadportion of the device is :1 lug 25' inclined outwardly from the or heavywire 15. Between center of the wheel and also toward a'vertiwithlaterally and inwardly inclined lugs links, and by securi g the .1

member 26 in posiiion.

29 designed to lit above and against the outer surfaces of the lugs 25as shown in l. The bodies 23 are rcvided as one end with an outwardly"'15 hip; 30, indicubed by dotted lines in ice figures and thecushioning members 26 are provided with notches adapted to receive thelugs In the assembling snd installation of my improved tire protector,the annular memhers 12 are placed in position on each side of the wheel,and she rods or "wires 15 are placed in the bearings 14.. The units maythen be assembled by securing 'cogether the to the body One of the lius, however, designed to be secured. to Wire or rod 15., should be leftsepara'lze from the rest oi" the unit. The cnd'link at one side cl theunit is then placed in position by sliding the liulr member 18 aroundthe W re 15 and the unit of the proteclor is placed on the tire. Theseparate link is their assembled on the Wire 1.5 on the opposite side ofthe Wheel and connected Willi 'iz'i'e proper liul; on the same side bymeans .01": e boll; 22. The cushioning member,

si'h'ioncu the member lie Wheel.

The member 556 is prefe iblyso made d somewhat, their resilicushion Thecushioning member 26, however, held. against sliding in one directioncircurnferz iifilly of 'the 26 iS-ill'lfill slid into po gvvlieel, bya/lug 30. llc may lie mencioned in this connection tliecfilie lug 30 isso loouted that the rotation of the Wheel through cllciorwerd .trevel ofthe machine tends to force the member 26 agemslz said lug 30.

The units are preferably placed close enough together so that thecushioning memi321 26 cannot travel longitudinally of the Wheel a,sufiicientdistance with relation so the members 23 to which they aresecured to be detached therefrom on account of the neXs adjacent unitsof the protector.

ll; Will be seen that any unit maybe quickly link may and easily removedfrom the Wheel by rile removal of one loolc 522, and lillfijl, anyloo-quickly and easily taken out and. repaired or replaced With a newlink.

By removing one bolt 22, the unit of which it forms a part may be swungclear of the Wheel, except at one end of the unit, and the member 26 maythen be slidebly removed for purposes of repair or replacement. f

The parts or my device are of simple and inexpensive construction, andmay "oe made in standard sizes, so that they may be quicklyinterchanged. o

l t-may be. mentioned in this connection that the members 12 and 15 maybe in various sizes for different sized tires, While the rest of theunits may be built up tofit. any tire by the addition of the links, andit is thus possible for the dealer to carry a, comparatively small stockby keeping on hand extra links, and at the same time to Be able to fitany tire that customers may have. 0

Changes may Joe made in the construction and arrangement of the parts ofmy proved. device Without departing from its essential. vfeatures andpurposes, endv it is my intention to cover by this application any"$11011- changes which may be included Within the scope of my claim.

I claim as my invention. 1

A tire protector comprising a plurality of tire protecting units, a,plurality of detachable members designed to be slidebly mounted cu saidunits by a movement circumferentielly of the tire flexible devicesconnected with each of said first named units designed to extendsidevvise around the tire, means for securing the inner ends of saidflexible devices at the felly of a Wheel in position spacedcircumferentially .of the wheel, So that said second described members.cannot slide longitudinally of the tire for becoming free from therespective first described members Without coming in contact withadjacent tire protecting members.
